I had a weird day today. My LFS tested my water, and was high on phosphate and a spike on nitrite, which both sounded weird to me. I brought my water to the fancy shop, nitrite and phosphate came up clean but ammonia was high. Everybody still seems happy so I am going to bring a water sample in to a 3rd shop tomorrow and do my weekly water change since it's due.
Don't think I have anything to worry about, probably just some bunk tests, or we can hope at least. I haven't added anything that would cause a cycle so I think it's just a fluke.
